Earlier quoted context omitted.
Every learning method you can think of has been thought of before and all variations have been implemented in classrooms throughout time. It is mostly pseudo-science. You either put in the effort to learn and struggle until you succeed or you don't. There is no secret sauce.
This isn't true. I put in a great deal of effort in college and struggled to learn. After college I changed the way I interacted with information, and found that I could learn and remember orders of magnitude better by using studying and practice techniques that mapped more closely with how I thought about information.
And when I say learning, I mean understanding the material, not just remembering a bunch of information for an exam.
